I needed to send back as I needed a two stage regulator. That was what I thought I was ordering. It was a single stage and would work for what I needed. Read the description carefully. Refunded without any problems. I would highly recommend as it was very well build and appeared to be durable. Reasonable for the money

Works good just wish it had everything to mount to the house and fittings for the gas lines but it did the job.

I used 2 of these off of a 3/4" tee pipe. One to a Pentair 400k BTU pool heater and the other to a Westinghouse 8900 watt generator. The output to the generator had a 3/4" to 3/8" compression fitting adapter installed on the regulator output and then a 3/8" propane extension hose fabricated with female ends. The generator started right up and the Pentair heater likewise. No adjustments to either device were needed or to this regulator. Very happy.

Plumbed in perfectly. Cheaper than having the old one recalibrated.

Good quality second stage regulator. Installed propane line to new generator and factory set @ 11 inches water column. Works fine from a known manufacturer.
